本实验观察了幼年大鼠视前内侧区（MPOA）、下丘脑前区（AH）和下丘脑腹内侧区（VMH）毁损对游戏打斗的影响。男性比女性更频繁地参与游戏战斗，并且没有任何病变可靠地影响这一措施。男性也发起了更多的游戏战斗。AH和VMH病变降低了两性的游戏开始频率，但MPOA病变对两性均无可靠影响。
The effects of medial preoptic area (MPOA), anterior hypothalamic (AH) and ventromedial hypothalamic (VMH) lesions on play fighting were studied in juvenile rats that were housed and observed in heterosexual groups of 6-8 animals. Males engaged in play fighting more frequently than females and none of the lesions reliably affected this measure. Males also initiated more play fights. AH and VMH lesions reduced the frequency of play initiation in both sexes, but MPOA lesions had no reliable effect in either sex.
